Observation of enhanced electron-ion recombination rates at very low energies.

摘要: A strong enhancement of electron-ion recombination over expected rates at sub-eV relative energies is revealed for highly charged ions. Measured Ne{sup 10+} and Ar{sup 13+} were found to be enhanced low ({lt}1 meV) by factors 4 10 theoretical predictions radiative rates, respectively. It shown that the majority in caused very lying {Delta}{ital n}=0 dielectronic resonances; nevertheless, nonresonant contributions measured both systems significantly higher than predicted presently available models. {copyright} {ital 1995 The American Physical Society.}
